DBS Manual - Revised April 2000

DBS-2.3/9.2-300

The DBS allows extensions to be grouped into paging groups numbered 00-
07. When you issue a page (by dialing #00-#07), you specify a paging group, 
so that your announcement is heard over the key telephones and Digital 
Single Line Telephones that are members of that group.  Paging groups often 
include people whose work is related.

External zone paging allows you to connect up to five speaker groups to the 
DBS.  Each speaker group is assigned to one of five paging zones (00-04).  
Zone 00 corresponds to group 00. When you page group 00, your page is 
heard over the All-Page Speaker(s) as well as all other external zones. Zones 
01-04 correspond to groups 01-04. For example, when you page group 02, the 
page is heard on the external speaker(s) assigned to zone 02. Paging groups 
05-07 have no external paging zones. 

If zone paging is not required, general paging relay terminals C (common), B 
(break) and M (make) are also provided. The relay terminals activate any  
time there is a page to an external page group. These are used when paging 
and UNA use the same paging amplifier system. (See notes for more 
information.)

• The paging amplifier, zone relays, and speakers are not provided with the 

DBS. They must be purchased separately.

• The maximum current for each zone paging terminal on the Connector 

Panel (Z0-Z4) is 50 mA; the resistance of the relay used for each zone 
paging terminal must be 2600 to 2800 Ohms.

• The contact rating for the UNA/General Paging “C” and “M” terminals is 

30V DC, 1 amp (maximum).

• Connector 4 (CN4) on the Connector Panel is used to connect the paging 

amplifier. The output impedance of CN4 is 600 Ohms; the loss/gain setting 
is 0 dB.

1.  Connect the paging amplifier to CN4 on the DBS Connector Panel. (See 

2.  Connect the paging speakers to the amplifier and relays.
